Plant extraction process capable of automatically adding extraction agent

Abstract

The invention relates to the technical field of plant extraction, in particular to a plant extraction process capable of automatically adding an extraction agent, the plant extraction process capable of automatically adding the extraction agent is based on an extraction device, and the plant extraction process capable of automatically adding the extraction agent comprises the following steps: step 1, weighing plants needing to be extracted; secondly, a box cover at the top of the equipment box is opened, needed plants are added into the inner wall of the equipment box, a solvent is injected into the equipment box through a solvent pipe, a hydraulic rod is started to push a piston plate upwards, the plants are immersed in the solvent on the inner wall of the equipment box, and at the moment, an electric heating pipe arranged on the inner wall of the piston plate is started to heat the solvent; and after plant extraction is completed, the piston plate is moved downwards, so that residues of the plants are retained at the top of the soaking filter screen, rapid solid-liquid separation is achieved, the quality of extracted products is improved, complex treatment of other related steps is not needed, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to a plant extraction process for automatically adding an extractant. Background technique [0002] Plant extracts refer to substances extracted or processed from plants (all or a certain part of plants) using appropriate solvents or methods. They can be used in the pharmaceutical industry, food industry, daily chemical industry and other industries. Plant extraction requires After crushing raw materials, dissolving, reacting, filtering, extracting and other steps. [0003] After retrieval, the Chinese utility model publication number is: CN211836433U patent discloses a plant extraction device, which can crush the material before extraction and sieve the material after extraction, and the screen at the bottom can be taken out and cleaned. The unit is easy to clean and service. [0004] But in prior art, still there is following problem: [0005] (1) During the extraction...

AI Technical Summary

Problems solved by technology

[0005] (1) During the extraction, the substances in the two states of solid and liquid in the equipment box cannot be separated well, which leads to the doping of solid impurities in the plant extract after extraction, which requires other related steps to be processed. lead to a reduction in the efficiency of extraction operations;

[0006] (2) In the prior art, the plant raw materials put into the extraction equipment are not crushed again, and there are some raw materials that are insufficiently crushed in the plant raw materials, which affects the subsequent extraction effect
